I only ask because I've got a new one I can't seem to shift with a can'o air (green, about 5 inches in diameter) . It only shows up in dark scenes, but it's bad enough that even my wife asked 'what's that green circle?'

Do you guys just live with them?

As I said, I tried to shift it myself last night. Took the lid off with the thing turned on, so I could see inside with it 'lit up'. There's *a lot* of dust in there on the optics you just don't see on screen (thank god, as it's pretty much impossible to shift. Even with an air can & hose ).

Trouble is, I reckon you can't get to some of the optics (without hardcore dismantling), which, I reckon, is where my green blob lives.

I'm seriously considering getting onto Sanyo directly, as it can only get worse over time.

Sounds like youv'e tried your best but there are a lot of comments there that might help.

If it were me I'd contact my dealer immediately, it just shouldent happen in the first place...should it?? I realise of course that heat, fans and dust dont mix, but if the problem exsists with many people, then surely Sanyo should get their thinking caps on and create a modification that helps.

Don't be daft man, use a kango - far easier

Yo've tried your best to shift it so I'd again suggest returning it to your dealer for service. No point in risking damage with open- heart surgery on a new unit now is there? (says he who'd his HS10 in bits in days, just for "craic").

well i have 3 big dust blobs......grrrrrrrrrrrrr! I didn't have any with my panny 200, which i had for 2 months, and my Z2 now has 3. They all came at the same time and it is really annoying in dark scenes. I will give it an blast some time this week. My bedroom isn't even dusty!i hoover it at least twice a week and dust most surfaces.really bloody annoying

I've found I can shift *some* of them with the air can, but not others (no matter how creativly I squirt...if you no what I mean )

I've got three as well (as of this afternoon); One's faint blue, which I don't mind too much. One's quite small & green (not ideal). And there's one fat daddy, giant haystacks, sumo green mother of a blob, which, as you can probably tell, irritates me a fair bit

My dust filters clean BTW.

I'm kind of loathed to contact Sanyo just now as it's practically new. I reckon I'm better off waiting a few more weeks to see if any others turn up (I'm pretty sure they will).

Let us know if your's shifts after a blast. If not I reckon we should start a group and mass email Sanyo as I reckon it's bound to be an ongoing problem for more & more Z2 owners.

Sooner or later even the most tolerant of them will get annoyed at 'green snow' when the screen goes dark

Image what the damn things going to be like in 11 months when the warrenty expires?!

yeah we should mass e-mail Sanyo, it is ridiculous. My filter is also very clean. The filter was one of the new and improved things of the Z2 and was meant to keep the internal optics dust free, well to a degree.
If i get one more, i have a fourth btw but it is very faint, i am calling up Sanyo and demanding a new one be sent or for it too be cleaned and sent back within the week.
i dunno, see how the air can does i suppose

Fingers crossed...... i have no dust just yet. Anyone cared to compare occurances of dust for table and ceiling configs?

If we are talking about the same compressed nitrogen canisters, blobs which wont move would be worrying. I use these things for cleaning silicon surfaces and it takes something to physically be bonded to the surface for it not to be removed..... that suggests any such 'dust' blobs are really very worrying indeed.

oh and in case anyone doesnt already know, i have talked to sanyo in length about all sorts of things Z2 related..... it was interesting, first that they are not willing to hand out any sort of service info, and second that they say certain things are issues which are 'inevitable' and are really not something they should be accountable for. Oh..... and their unwillingness to directly swap out..... apparently it is a nasty procedure..... service needs to get the machine, they need to check it, they need to do a report so that their finance can allow a replacement, hen they actually have to find a replacement..... not necessarily easy they said...... in other words they told me to go to my dealer who could fix it without all the BS!

So by all means whinge at sanyo, but if you want it done right, talk to your dealer.

Coffee table - no dust blobs yet <knocks on wood multiple times> though being a newbie to PJs it might be i dont know how to identify them properly

Could be the dust is just somewhere not being sprayed. Sounds more logical to me, because as you say, those things push out a mini-hurricane.

I reckon the problem with cleaning's down to accessability; with the lid off, you've got 3 slots in the top PCB to blast through, plus some limited access from the side.

Trouble is this just doesn't seem to be enough to get at all the bit's you need to...which is just plain daft.

You'd think with their experience they'd have realised at the design stage that dust was fairly inevitable, and made cleaning as straight forward as possible.

Inexcusable really

Anyway, I'm still not sure what to do about this. I've got the phone number of my nearest Sanyo authorized service centre (can't see a lot a point in hassling Ivojo??). Just in 2 minds if now's the best time to call them.

Banned

well if you can actually get hold of the service centre easily..... they will help you im sure..... but if you want a replacement, it would be quicker to go to ivojo (or whoever). For me, with distinct lack of service centres in NI, this was of course my only option.

Before people go fiddling with filters..... i suspect the best way to get a dust blob is to actually remove the filter, this stirs up the one area you KNOW dust to be present and in the path to the panels....

True, but you do have to remove the filter to check it/clean it! Fortunately (judging by the state of mine after about 70 hours) the service interval could be at least circa 6 months or 400 hours

I would go the dealer first as well - I am sure Ivojo will be helpful.

I think not checking the filter is more risky than checking it because of the increased danger from dust building up on the filter and causing either overheating of the unit (= shorter bulb life or even pj going adjustable feet up) or else one day you knock the pj and dislodge built up dust which then goes into the projector.

Thinking about it - it might be better to check and clean the filter more often to reduce the risk of either of these things happening or even the possible dislodgement of built up dust when you do check the filter!! Maybe someone could do a risk analysis on all this

Guest

Ok so does everyone feel that the dust is getting in through the filter end of things or is it more likely to be getting in from the front?

I have two blobs of a bluish colour maybe more purple than blue but still bloody annoying but only visible on dark scenes.

After inspecting my filter it looks as clean as a new pin to me and the vents are also dust free. The first blob I noticed is at the bottom and almost out of the viewing area of the screen and appeared after just a couple of hours of use. The other one appeared a few days ago and after 80 hours of use.

The area at the back of the lens looks like it has some gaps for dust to get in. Would it hurt to cover the lens shift dials once the projector is set up with some tape or something? Or maybe even getting a clear piece of glass or some other material cut to size to cover the dials and lens area when the projector is in use (like the HS10 has ) it could be easily be removed to shut the front. Or maybe something thinner could be used so it could be taped permanently into place. Or has anyone got any better ideas?
